The 35 best GEO agencies
If you want to be visible on ChatGPT, Perplexity, Google AI Overviews or AI Mode, Gemini or Copilot , you need more than just traditional SEO. GEO (Generative Engine Optimisation) specifically optimises websites and content so that they are understood by generative search systems, recognised as a trustworthy source and cited in responses. This shifts the focus: visibility is no longer determined solely by Google rankings, but also by whether content is technically accessible to AI systems and has been prepared in a way that is semantically unambiguous, authoritative and suitable for citation.
But which providers have truly mastered this new discipline? Our comparison of the best GEO agencies in Germany directly compares the relevant providers and examines, amongst other things, their GEO portfolio, technical and content-related services, off-page measures, as well as the quality and scope of client reviews. This reveals which agencies have already established a comprehensive GEO offering and where their service profiles differ.
Key points at a glance
- Not every GEO agency is right for every business: the key factors are the starting point, internal resources, technical requirements and the desired scope of services.
- A good GEO agency should offer more than just content: technology, entity optimisation, structured data, AI crawler accessibility, off-page signals and monitoring are alsoimportant .
- Our comparison covers 35 providers: weassess reputation, on-page and off-page GEO, specialisation, measurability and supplementary services.
- The rankings are based on fixed criteria: reputation and scope of services are factored into the overall result on a weighted basis; there is no editorial self-promotion.
- Ratings alone are not enough: high customersatisfaction is important, but says nothing about the depth of the actual GEO services.
- The best choice is the agency with the right service profile: for some companies, technical GEO expertise is key; for others, it’s full-service support, digital PR, content or strategic consultancy.

Methodology of the comparison
Reviews as a key basis for comparison
We use ProvenExpert as the key basis for evaluating GEO agencies. The reason: in the age of AI, visibility and trust are no longer determined solely by a brand’s reputation on Google. What matters far more is the overall picture of a brand across various platforms and sources. ProvenExpert aggregates reviews from various connected portals, thereby creating a broader basis for comparing public reputation.
An agency’s own reputation as an indicator of quality
The agencies’ own reputation-building efforts are also factored into the assessment. Anyone advising companies on GEO, brand authority and digital visibility should also actively monitor and consistently maintain their own reputation. For potential clients, this is a further indication of how systematically an agency handles trust, authority and brand signals.
Quality and quantity of reviews
The ranking of providers takes into account both the quality and the number of reviews. A high average rating is therefore not considered in isolation. The volume of reviews, as well as discernible positive and negative experiences, are also factored into the ranking. Agencies without a usable ProvenExpert profile were not excluded. However, as there is no standard basis for comparison for them, they are ranked more cautiously in terms of trust and objective comparability.
Scope of the GEO portfolio
In addition to reputation, we assess the scope and depth of the GEO portfolio. In doing so, we consider both on-page and off-page measures. These include, amongst other things, technical AI crawler accessibility, structured data, entity optimisation, content optimisation, citations, brand mentions, digital PR and external authority signals.
Scaling through complementary services
We also take into account what additional services are offered to scale a GEO strategy. These include, for example, SEO, content marketing, digital PR, web development and paid media. A broader service portfolio can enable GEO to be integrated more effectively into an overarching visibility and growth strategy.
Why is DREIKON ranked third in its own ranking?
Openness and honesty are our top priorities in this comparison. That is why we do not automatically place DREIKON in first place simply because we are publishing the comparison ourselves. The ranking is based on the established criteria and is intended to remain as transparent as possible. We want to impress through our actual performance – not through a ranking that has been manipulated in our favour.
We therefore do not see DREIKON’s current third-place position as a disadvantage, but rather as an incentive. Particularly in the age of AI, GEO and rapidly changing search systems, standing still is not an option. Our aim is to continuously develop our services, processes and methods.
Now it’s your turn: What does your business need to boost its AI visibility?
You don’t need another general assessment, but rather clarity on which GEO measures actually make sense for your business. That is precisely what we will clarify with you: where do you currently stand in terms of SEO and AI visibility, what internal resources are available, and where would external support be worthwhile? In a no-obligation initial consultation , we’ll work with you to determine whether you need one-off advice, a GEO audit or ongoing support, and whether DREIKON is the right partner for this.
Frequently Asked Questions about good GEO agencies (FAQ)
A GEO agency optimizes content for generative search systems (AI response engines) and ensures that brands appear correctly, visibly, and quotable in AI responses.
SEO optimizes for classic search results, GEO for AI-based answers. A modern GEO SEO agency masters both disciplines.
No. GEO complements SEO. Without clean SEO, GEO is not sustainable.
A good GEO agency combines traditional SEO expertise with optimisation for generative search systems such as ChatGPT, Gemini, Perplexity, Google AI and others. It takes a data-driven approach, ensures its methodology is transparent, and takes into account not only content but also technical factors, entity signals, structured data, external mentions and digital authority. Also important are transparent monitoring, clear success criteria and a service model that suits the company’s specific situation.
An effective GEO agency should cover a GEO audit, content creation and optimisation, entity optimisation, structured data and ensuring a website’s accessibility for AI crawlers. Depending on the strategy, this may also include prompt research, grounding pages, digital PR, citations, brand mentions, link building, competitive analysis and AI monitoring. Combining GEO with SEO, content and technical optimisation is particularly beneficial.
The cost of a GEO agency depends on the scope of services, the size of the business and the starting point. A one-off GEO audit is generally cheaper than ongoing support covering content, technical optimisation, digital PR and AI monitoring.
